DENVER, Colorado (CNN) -- Democratic presidential nominee Sen. Barack Obama called his acceptance speech on Thursday "the American Promise." It included a list of promises for change that he said, "We need right now."

• Make it easier for Americans to afford U.S.-built, fuel-efficient cars.

• Have the federal government "invest $150 billion over the next decade in affordable, renewable sources of energy -- wind power and solar power and the next generation of biofuels." Doing so, he said, would "lead to new industries and 5 million new jobs that pay well and can't ever be outsourced."
